You voted, so here it is. I tried to condense everything you might need to know to get going with writing Python interfaces to C++ code. The breakdown is
0:00 Intro
0:39 Absolute minimum example
2:28 Exploration of generated module
3:25 Classes
4:49 STL containers, Python types
6:20 Numpy support
7:24 Properties
8:00 The GIL
